Q I Hear the police are trying to crack down on people driving on drugs, though I don't understand how.

Does this mean I could get arrested for driving after taking too much Lemsip?

And would driving after smoking weed be treated in the same way as if I'd had five pints down the local? - Barry Redcliffe, Southend

A there's lots of talk coming from the Government and the police, but not much action. One of the main problems for the authorities is that there is not a reliable drug-tester, as there is with alcohol.

Police officers give roadside recognition tests in which the driver is required to undergo a number of simple co-ordination tests to see if they have taken drugs.

Of course, these are not conclusive.

I would not condone drug-driving, but there are already laws in place alongside the drink-driving laws which carry pretty strong punishments.

But I believe the authorities should try to concentrate on informing and educating all of us about the dangers of drugs... instead of just looking at how to punish people.

Prevention is surely better than cure... and that applies to road-safety policy generally.
